C340 driver package for Mac

I am about to re-install the C340 driver package for Mac. I am running OSX El Capitan on a Mac mini & wonder which driver package I should install to use with my Sculpfun s6pro.since there are three versions (V1.3.1.4 & 1.5) available? I currently have V1.3 installed but need to repeatedly plug & unplug the laser USB connection until it is recognized, after which it performs as expected. I am hoping a re-install might improve the connection issue.
Thanks,
Ted.
